      hw/pci*: Replace fprintf(stderr, "*\n" with error_report() · 0151abe4
      由 Alistair Francis 提交于 
      Replace a large number of the fprintf(stderr, "*\n" calls with
error_report(). The functions were renamed with these commands and then
compiler issues where manually fixed.

Some lines where then manually tweaked to pass checkpatch.

      spapr/pci: populate PCI DT in reverse order · a8eeafda
      由 Greg Kurz 提交于 
      Since commit 1d2d9742 "spapr_pci: enumerate and add PCI device tree", QEMU
populates the PCI device tree in the opposite order compared to SLOF.

Before 1d2d9742:

Populating /pci@800000020000000
                     00 0000 (D) : 1af4 1000    virtio [ net ]
                     00 0800 (D) : 1af4 1001    virtio [ block ]
                     00 1000 (D) : 1af4 1009    virtio [ network ]
Populating /pci@800000020000000/unknown-legacy-device@2

7e5294b8 :  /pci@800000020000000
7e52b998 :  |-- ethernet@0
7e52c0c8 :  |-- scsi@1
7e52c7e8 :  +-- unknown-legacy-device@2 ok

Since 1d2d9742:

Populating /pci@800000020000000
                     00 1000 (D) : 1af4 1009    virtio [ network ]

                     00 0800 (D) : 1af4 1001    virtio [ block ]
                     00 0000 (D) : 1af4 1000    virtio [ net ]

7e5eadb8 :  |-- scsi@1
7e5eb4d8 :  +-- ethernet@0 ok

This behaviour change is not actually a bug since no assumptions should be
made on DT ordering. But it has no real justification either, other than
being the consequence of the way fdt_add_subnode() inserts new elements
to the front of the FDT rather than adding them to the tail.

This patch reverts to the historical SLOF ordering by walking PCI devices
in reverse order. This reconciles pseries with x86 machine types behavior.
It is expected to make things easier when porting existing applications to
power.

pci_nic_init_nofail may release the object if device fails to
initialize which leads to use-after-free in error handling block.
qdev_init_nofail does the same thing while holding the reference.

      pcie: fix link active status bit migration · 6b449540
      由 Michael S. Tsirkin 提交于 
      We changed link status register in pci express endpoint capability
over time. Specifically,

commit b2101eae ("pcie: Set the "link
active" in the link status register") set data link layer link active
bit in this register without adding compatibility to old machine types.

When migrating from qemu 2.3 and older this affects xhci devices which
under machine type 2.0 and older have a pci express endpoint capability
even if they are on a pci bus.

Add compatibility flags to make this bit value match what it was under
2.3.

Additionally, to avoid breaking migration from qemu 2.3 and up,
suppress checking link status during migration: this seems sane
since hardware can change link status at any time.
